Location: Lambeau Field, Green Bay, Wisconsin
Teams involved: Green Bay Packers, New York Giants
The level of dedication that Green Bay Packers fans have for their home team is, at this point, insane. When a tremendous snow storm threatened to postpone the NFC Championship Game between the Packers and the visiting New York Giants in 2012, the Green Bay community rallied together to shovel out Lambeau Field in time for that Sunday's game. Granted, they were paid $10/hour for their services, but it's still impressive that 1250 people showed up to help out. Unfortunately for many, the Packers could only take 400 volunteers.
Even worse for Green Bay fans, the Giants ended up taking the Packers to the woodshed, winning the game 37-20. Maybe they should've kept some of that snow around. Clearly, any home-field advantage would've helped.
